208 ■ NATURAL HISTORY OP PLANTS. 



Knear subulate compressed, somewhat spirally twisted, stigmatose. 

 Fruit drupaceous, finally sub-dry, sometimes adnate with calyx; 

 seed exalbuminous ; cotyledons of subglobose embryo thick sub- 

 equal ; radicle short superior. — Lactescent trees generally pubescent ; 

 leaves distichous, unequal at base ; stipules connate in one supra- 

 axillary oblong-acute ; inflorescences axillary stipitate, fasciculate or 

 rarely few or solitary, 1-sexual. {Central America, Cuha^) 



43 ? Helicostylis Teec^ — Flowers dioecious (nearly of CasUlloa) ; 

 the males crowded in polyphyllous involucre sessile ; the females go 

 on common receptacle. Male calyx 4-phyllous. Stamens 4, 

 oppositipetalous ; anthers extrorse. Female calyx 4-phyllous. 

 Germen relative to calyx inferior and hence adnate to foveoles of 

 receptacle ; ovule, etc., of CasUlloa; style branches 2, linear subulate, 

 compressed, much twisted spirally. —A lofty tree; leaves distichous; 

 stipules 2, axillary acuminate subamplexicaul ; inflorescences, etc., of 

 CasUlloa ; ^ folioles of involucre close deltoid, in many places imbri- 

 cate. [Guiana, north. Brasil.*) 



44 ? Noyera Teec.^ — Flowers dicecious (nearly of CasUlloa) ; 

 males...? Female flowers oo (15-30), collected on a common 

 subplane receptacle involucrate with imbricate pluriseriate bracts, 

 imbedded in its foveoles ; calyx urceolate, with small perforation at 

 upex. Germen semi-inferior, 1-locular; ovule inserted a little below 

 apex of cell, descending; micropyle extrorsely superior; style 

 branches 2, filiform subulate. Fruit, etc., of CasUlloa ; coat of de- 

 scending seed membranous (fuscate) ; cotyledons of subglobose exal- 

 buminous embryo thick hemispherical subequal ; radicle very short 

 superior. — A ferruginous tomentose tree ; leaves distichous ; stipules 

 axillary opposite amplexicaul ; scars annular ; female inflorescences 

 axillary solitary subsessile.® [French Guiana?)
